Nuclear division is the process by which the nucleus divides. There are two types of nuclear division, mitosis and meiosis.
-
A nucleus needs to divide its DNA before it is replicated. This is to ensure that all the daughter cells have the genetic information to produce the enzymes and other proteins that they need.
The replication of DNA is through the semi-conservative model. Half of the original DNA is built into the new DNA strand.
-
- The four types of nucleotide, each with their bases of Adenine, Guanine, Cytosine or Thymine, must be present.
- Both strands of the DNA molecule for the attachment of these nucleotides.
- A source of chemical energy.
- The enzymes DNA polymerase and DNA helicase.
